Title: Process for the preparation of organophilic oxides and chromate pigments
IPC: C09C3/08
Filed: 1960-05-10
Abstract: Oxide, hydrated oxide, and chromate pigments are rendered organophilic by reacting an aqueous suspension of the pigment with a solution of an anionic surface-active agent, acidifying, separating the pigment, drying, and, if desired, disintegrated the product thus obtained.  The surface-active agent may be an alkali metal or ammonium salt of a fatty acid which may contain -OH groups, e.g. ricinoleic acid, or which has at least 8 carbon atoms.  The salts of industrial stearine or of partly polymerized unsaturated fatty acids may also be employed.  Also suitable are alkali metal salts of alkyl-, aryl-, or alkyl-aryl-sulphonic acids.  The acidification may be effected by a mineral acid, e.g. HCl, H2SO4 or H3PO4, or by strong organic acids, e.g. acetic acid.  Pigments referred to are titanium dioxide, red and yellow iron oxides, green chromium oxide, red bauxite (obtained by heating bauxite), aluminium oxide, zinc chromate, zinc tetroxychromate, lead chromate, and basic lead chromate, barium chromate and strontium chromate.

Title: Improvements in or relating to radio receivers for radar echo signals
IPC: G01S7/34
Filed: 1945-06-28
Abstract: 598,672. Automatic gain control ; radiolocation. DUNWORTH, J. V. June 28, 1945, No. 16558. [Class 40 (v)] In a radio receiver for radar echo signals there is provided a normally-blocked A.V.C. unit, which is opened by means of gating impulses coincident with the chosen echo signals. In a branched A.V.C. amplifier, recurrent trains of negative-going echo signals are applied to the grid of the valve VI, the amplitude being adjusted by means of the variable resistance R1. The valve V1 is run at saturation level, signal pulses of above a predetermined amplitude causing positive-going impulses to be applied to the inner grid of the valve V2. The resistances R3, R4, R5 apply positive bias to the cathode of the valve V2 from the H.T. line, the outer grid being grounded over the resistance R6. The anode of the valve V2 is normally non-conductive, conduction occurring when a positive pulse on the inner grid coincides with a positive strobe pulse which is applied to the outer grid via the terminal 2. The outer grid is prevented from becoming positive relative to the cathode by means of the diode V3. Successive negative pulses are passed over the diode V4 4 to the circuit C1, R7, the steady potential being applied over the smoothing network C2, R8, R9 to the grid of the cathode follower V5. The cathode of the valve V5 is connected to the negative line 4 over the resistance R12, A.V.C. potentials being taken off over the smoothing network C3, R10, R11, R12. The A.V.C. potential is limited to negative values by means of the diode V6, and in the absence of signals is determined by the potentiometer P1. The switch 3 and adjustable potentiometer P2 permit of alternative manual control. Specifications 581,996, 582,325, 582,503 and 598,649 are referred to.

Title: Winding apparatus
IPC: B29D30/00
Filed: 1974-04-16
Abstract: 1470221 Making tubular tyres CATERPILLAR TRACTOR CO 16 April 1974 [16 April 1973] 16595/74 Heading B7C [Also in Division B8] To wind flexible elongate material about the body of a toroidal member, the member is supported rotatably and vertically on rollers connected to a base by means ensuring continuous support for the member while compensating for the increase in size of the member due to the winding. As shown, Fig. 1, toroidal member 22 is rotatably supported on rollers 34 and is surrounded by guide means 120 for winding material about the rotating core. Pairs of rollers 34 are mounted on two arms, e.g. arms 44, each pivotably mounted on two arms, e.g. arms 40, each pivotably mounted on two arms 38 or 54 which are pivotally mounted on base 24. At least one roller, e.g. the four middle rollers, is or are driven by a reversible, variable speed drive to rotate member 22. On either side, a spring 74 acts on a rod 70 pivotably connected to arms 56 or arms 40 to lift the lower rollers. The rollers are spaced about the member's periphery at unequal intervals, and the distance between the rollers of each pair may be varied by means of a wedge system. Guide rollers 122, each mounted on an upwardly pivotable arm 124, engage the member's front and rear. Base extension 28 supports a horizontal C-shaped frame 144, Fig. 4, supporting annular structure 146 and annular cam 180. Structure 146 has support rollers 168 and guide rollers 166 supporting and guiding annular gear 170 which is rotated, in either direction, by the motor driving rollers 34. The structure, cam and gear have gates 148, 186, 172 pivotable to allow the member 22 to be placed on the rollers and within the gear and C-shaped frame. Gear 176 carries, Fig. 6, reel support 208, feed spool 306, reel 302 and pressing roller 268. To wind on extensible material R from a reel on support 208, the material is bonded to the member's surface and air jack 270 is extended to pivot roller 268 so that, with rotation of gear 170, the roller's soft surface rolls on the material to press it on to the member which is itself rotating on rollers 34. Feed spool 306 is rotated via belts and a chain by the rolling of roller 268 to feed the material at a speed less than that with which it is wound on, to thereby extend the material. Reel 302 is similarly rotated via a slipping clutch to wind up material backing B. Inextensible filament W is similarly wound on, being pressed on to the member's surface by roller 250 pivoted by air jack 258. Increasing filament tension pivots lever 224 against spring 234 to lessen the effect of brake block 230 on reel support brake plate 212. Filament guiding sleeve 207 is pivoted with lever assembly 196 by the rolling of lever roller 202 on stationary cam 180 to compensate for the non- circular cross-sectional shape of the member. To form a tube-tyre, rubber and wire are wound on to a disintegratable sand core of oval cross-section.
